Judges 1:33Naphtali failed to drive out the inhabitants of Beth-shemesh and Beth-anath. So the Naphtalites also lived among the Canaanite inhabitants of the land, but the inhabitants of Beth-shemesh and Beth-anath served them as forced laborers.

Judges 1:35And the Amorites were determined to dwell in Mount Heres, Aijalon, and Shaalbim. But when the house of Joseph grew in strength, they pressed the Amorites into forced labor.

Treasury of Scripture

And the Amorites forced the children of Dan into the mountain: for they would not suffer them to come down to the valley:

Judges 18:1 In those days there was no king in Israel: and in those days the tribe of the Danites sought them an inheritance to dwell in; for unto that day all their inheritance had not fallen unto them among the tribes of Israel.

Joshua 19:47 And the coast of the children of Dan went out too little for them: therefore the children of Dan went up to fight against Leshem, and took it, and smote it with the edge of the sword, and possessed it, and dwelt therein, and called Leshem, Dan, after the name of Dan their father.

Forced the children of Dan into the mountain.--The condition of this tribe was, therefore, the worst of all. So far from reducing under tribute the Canaanites of its assigned possession, as the central tribes did, the Danites did not even succeed in establishing a tolerated neutrality among them, like the northern tribes, but were driven into a few mountain-strongholds. It was probably this failure, and the consequent pressure of space under which the tribe laboured, which induced them to undertake the successful northern expedition alluded to in Joshua 19:47 and described in Judges 18

1:21-36 The people of Israel were very careless of their duty and interest. Owing to slothfulness and cowardice, they would not be at the pains to complete their conquests. It was also owing to their covetousness: they were willing to let the Canaanites live among them, that they might make advantage of them. They had not the dread and detestation of idolatry they ought to have had. The same unbelief that kept their fathers forty years out of Canaan, kept them now out of the full possession of it. Distrust of the power and promise of God deprived them of advantages, and brought them into troubles. Thus many a believer who begins well is hindered. His graces languish, his lusts revive, Satan plies him with suitable temptations, the world recovers its hold; he brings guilt into his conscience, anguish into his heart, discredit on his character, and reproach on the gospel. Though he may have sharp rebukes, and be so recovered that he does not perish, yet he will have deeply to lament his folly through his remaining days; and upon his dying bed to mourn over the opportunities of glorifying God and serving the church he has lost. We can have no fellowship with the enemies of God within us or around us, but to our hurt; therefore our only wisdom is to maintain unceasing war against them.
